Re: Double Roller Trigger for Pathos handle, Ermes Sub

You can clearly see the space where the old pin release was.

Actually that is a very good point. The old pin line release slots do match up with the approximate location of the back roller slot. So for sure adding a 14mm pin would be a solution to avoid the tilting of the back roller. The slot on the Pathos handle is slanted so you need to make sure that if the pin touches the frame, just to shave or file off that area. Obviously this is not a solution you want on a brand new trigger, as you don't really want to have pins sticking out of the box, but it will at least get the back roller from twisting for now.

I made a 6.8 roller and tried it ... helps a little but unfortunately it also can twist and wedge. A 6.8 roller with a 14mm pin would certainly work Long term, most likely the frame of the box needs to have the oval cut for the roller trigger about .7mm lower. to keep the CG of the pin below the 3 mm wider part on top. For existing boxes you could do the same thing by using a thicker

I found another problem with the front roller also. The edges have chamfers that make the actual roller contact area with the trigger sear much less. This was a big no no with our DR testing. So most likely this has to also change to a wider and flat edged roller.

Just feels that this is a trigger in the alpha stage. The idea of the floating roller is a completely new and revolutionary idea. But it still needs to be tested to make sure it works well under high loads and multiple loading cycles. There is always the possibility that it might actually not work or at least needs a lot of tweaking to get it to work.
